AERIAL ELECTRIC LINE.

Specification of Letters Patent.

Patented June 18, 1912.

Application filed March 9, 1912. Serial No. 682,736.

T 0 all whom it may concern:

Be it known that I, VVILHELM ELLINGEN, a subject of the German Emperor, residing at Cologne-Lindenthal, Germany, have invented new and useful Improvements in Aerial Electric Lines; and I do hereby declare the following to be a full, clear, and exact description of the same.

My present invention relates to improvements in aerial electric lines and has for its object to provide means whereby a plurality of lines of diiferent polarities may be suspended in long spans and at the usual distances apart from each .other without the swinging lines touching one another.

According to my invention I attain this result by giving the various lines different sags, the differences between the sags being determined as follows: Assuming two wires suspended at a distance L from each other, the swinging diameter of one of these wires being R, and the distance, at which the two wires must be held owing to the existing span for avoiding short-circuiting, being S, the swinging diameter of the second wire must be in order to prevent the same from coming into contact with the first wire while it is swinging. If a third wire is suspended at a distance L from the second wire, the swinging diameter R of this third wire must be Suppose L:L and substitute for It its equivalent value, then In the accompanying drawing I have shown three lines in long span, and in this drawing Figure 1 is a side elevation of the lines, and Fig. 2 is a vertical cross-section on line aa of Fig. 1.

As shown in this drawing the wires 1, 2, 3, are suspended so that the sag thereof is of different height according to the principle described above.

In Fig. 2 I have shown the circular ways through which swing the wires. The drawing shows clearly that the swinging wires cannot come into contact with one another.

Having fully described the nature of my invention, what I claim and desire to secure by Letters Patent is:

1. Aerial electric lines, comprising a plurality of wires, the sag of which is of different height according to the distance between the various wires.

2. Aerial electric lines, comprising a plurality of wires of different sags arranged so that the circular ways through which the wires are moved, do not cross one another, substantially as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
